Compact I/O Architecture and Application Scope
This compact I/O module provides versatile digital and analog signal handling for Modicon TSX systems. It combines 16 digital inputs and 16 digital outputs in a single unit. The module also offers two analog inputs for simple process measurement. This all-in-one design saves valuable cabinet space and reduces component count. Consequently, it suits small to medium-scale automation applications with mixed I/O requirements.

Digital Input Signal Processing
The ASBSIM216 captures 24 VDC signals from sensors and switches. Each digital input includes a debounce filter for reliable reading. The module updates input status within 2 ms for responsive control. Input data transfers to the controller through the bus interface. This ensures accurate and timely signal detection.
Digital Output Control and Actuation
Sixteen transistor outputs provide 24 VDC at 0.5 A for field actuators. Each output includes short-circuit protection for fault tolerance. LED indicators display the real-time on/off state for every point. Users can configure safe state behavior during communication loss. This protection safeguards connected devices effectively.
Analog Input Measurement
Two analog inputs handle 4–20 mA or 0–10 V signals from transmitters. The 12-bit ADC provides adequate resolution for basic process monitoring. Each channel includes filtering for noise rejection. This enables simple analog measurement without additional modules.
Installation and Maintenance
Insert the module into a TSX I/O slot. Secure with retaining clips. Wire the terminal block before insertion. Replace the module if channels fail.
